Definitions
- Anti-PSA goat IgG (2mg) was adjusted to a final volume of 1.25 mL with 50 mM borate (pH 8.5) in a test tube. This solution was added dropwise to the 1.25 mL of activated latex solution and stirred for 90 minutes at room temperature. 10 uL of 1M ethanolamine was added, followed by stirring for 30 minutes to quench the reaction and the addition of 100 uL of 5% (w/v) BSA with an additional 30 minutes of stirring to block any unbound binding sites.
- the data of Table 2 demonstrate high reflectance in the capture band in the absence of PSA when an interfering serum is used as the sample.
- the interference is eliminated by the addition of normal goat IgG, and, unlike the case in which the latex is conjugated with only goat anti-PSA (that is, biotin was absent), the reflectance in the collection band remained constant.
- the interference is substantial in the absence of added goat IgG, providing a clearly false positive.
- goat IgG is added, the interference is removed, but the collection band containing NeutrAvidin is effective, while in Table 1 the collection band gave no reading.
- the non-interfering serum gave a small reading for PSA captured, but this result is considered to be a low level background signal.
- Example 2 The procedure of Example 2 is repeated, except that the latex-labeled anti-PSA goat antibody and goat IgG are dried on the test strip in a form that can be resuspended before the first band containing immobilized anti-PSA monoclonal mouse antibody.
- the strip When the strip is partially immersed in the serum sample, reaction between the PSA in the sample and the anti-PSA goat antibody occurs on the strip.
- the sample migrates through the capture band where the bound anti-PSA goat antibody labeled with latex particles is also bound to the anti-PSA mouse antibody. Thereafter the sample migrates to the second collection band where the remaining unbound anti-PSA goat antibody labeled with latex particles is recovered by biotin on the latex binding to NeutrAvidin immobilized on the second band.
